Improvement in water-heating apparatus



JOHN C. RYAN, OF CHICAGO, ILLINOIS.v

Specification i'orming part of Letters Patent No. 83,552, dat-ed October27, 1868.

To allwhom' it may concern:

Be 1t known 4that I, J oHN C. RYAN, of Ohicago, in the county of Cookand State otIllinois,

have invented a new and Improved Water- Heating Apparatus 5 and I dohereby declare that the follo win g is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, referencebeing had to the accompanyingdrawings,forming part of this specification. l

The object of this invention is to .provide an apparatus for `heating`water and circulating the same, to obtain the greatest amountxof steamheat or hot water from the fire of an-ordinary stove.

It is designedfmore particularly for .shop

and household use, though it is equally'applicable in situations -Whereit is desirable to economize fuel and utilize the heat of one stove forwarming other parts of the building. lt `consists of a boiler containingwater, and

.being provided with a coil of pipe, one end of which communicates witha tank or reservoir, and also with the bottom of the boiler, While theother end communicates with t-he boiler at sonic point below the generalwater-level of the saine. The coil is thus incominunication i with theboiler and wit-h the source 0f supply,

so thatI the level otl water lin the boiler can be maintained. The bodyotthe coil is located within an ordinary upright cylindrical stove. rIheturns of' the coil pass around and against V the wall ot' the stove, andat that part usually ing it back to the eoil, and which, with otherdevice-s, perfecting the whole, is duly set forth in the following. I Sis the stove, and T and M the pipe and door of the same. rlhe coil B. isshowlfby re- 4 movinga portion of the s'tovebelow the door.

C is the supply-pipe leading from the tank Q, and is provided withcocks, a cock or globeVV valve, y, for regulating the supply from thetank, Aand a cock or valve, a, for regulating the rapidity of thecirculation, so that the water irl the boiler can be maintained at anydesired temperature within ordinary limits.

The-short pipe `U connects thel pipe C wit-hA the bottom ofthe boiler,and allows the water to circulate from the boiler through the coil.

The boiler is supported by the base N and branched rods o o, or by othersuit-able means, and is provided with gage-cooks l land a glass gage, J,connected with the top and bottom by pipes-K K,.all ot the usualconstruction.

The pipe E leads from the pipe D between lthe coil and boiler to theheater H, which may beplaced in'auy room or equivalent position as awarming apparatus. The pipe E is aises connected lwith the top of theboiler by two pipes, L and G.

The pipe I is provided with a cock or globe, valve, e, and the pipe G issimilarly provided with a cock or valve, c, both of which are be tweenthe pipe E and the steam-space ot' the boiler. y The pipe E is likewiseprovided with a cock or valve, d, which is betweenjts june tion of thepipes L and G.

' A pipe, I, connects the heater II with the vpipe C near the coil Il,at which point is ncock, m. The cock h is for the purpose oi' drawingoli' the water from the coil and boiler when not required. l

The tank is supplied from the general watersource by a pipe, R, and thesupply is regu lated .with the wellknown iloat-ball and cock, as shownatf.

1? is a safety-valve, weighted to any desired pressure. p

The operation of the apparatus is as follows The Water in the boiler,heilig' duly heated, supplies steam' tothe heater II, which is takenfrom the pipe Dthrough the pipe E, the valve d being setto regulate thequantity at will. The condensed steamfrom the heater is re-y turned tothe coil by the pipe Land discharged therefrom by means ofthe cock h..It' desired,l this cock maybe closed and the blow-ott' cock m opened,which will open communication from thepipe I tothe coil. The pipe L alsoadmits steam to the heater H when less degree et' heat is required, inwhich case the safety- FFICE. g

valve weight will be adjusted to exert lighter pressure on its valve.

The pipe G relieves the water in the coil from any beek-pressure; Aandobvia'teslthe spluttering andsnapping noise in the boiler 'which wouldotherwise occur.

I claim as new and desire to secure by Letters Patent- The combinationof the pipes E D L C with the boiler A, stove S, and coil B, whereby thecirculation of Water is effected, as above described, and' at the semetune the steam 1s taken from the pipe D or vessel A and conveyed to theheater H, as herein set forth, for
